Wow.

IE9 is coming, and it looks like it’ll get Microsoft back in the game. Full Developer Guide.

The Good: New standards supported, hardware-accelerated canvas, SVG, Javascript speed on par with the other browsers, preview installs side-by-side with IE.

The Bad: Not available on XP and no guarantee it will be. XP users will be stuck with, you know, all the other browsers that run their demos fine.
